Properties And Uses Of Chromium Oxide Green



Chromium Oxide Green pigment known as chrome oxide green. there have numerous preparation of chrome oxide process. but basically has three kinds: by chromium hydroxide preparation technique of chrome oxide green, ammonium sulfate sodium chromate salt decomposition method, Chromium Oxide Green direct decomposition method.

The thermal decomposition of ammonium sulfate sodium chromate salt, is the United states of america, Britain, Germany as well as other nations and also the basic techniques of production of chrome oxide green, has turn out to be the largest output in preparing chrome oxide green, very best high quality, most varieties of production methods. its benefit is relatively simple production procedure, cost lower than that of chromic acid decomposition technique, wide adaptability, started within the rotating mass production. the production process of basic does not produce harmful gas. chromic acid decomposition technique quick in current years . using the consciousness of Chromium Oxide Green. chromic anhydride in 1999 produced chrome oxide production twice about chromium.

The physical properties of chrome oxide green. chrome oxide green with metallic luster. colour is light green to dark green. magnetism,covering power is powerful, higher temperature resistant, weather resistant, insolube in water, in the atmosphere is stable. excellent weatherability, meet thermal stability, melting point 2265 degrees celsius, the boiling point of 3000 degrees celsius, is of high quality refractory materials. chrome oxide green chemistry, insoluble in water, acid and organic solvents, slightly soluble in concentrated sodium hydroxide answer, soluble in hot or boiling sodium bromate answer of sulfur phosphorus mixed acid, great paint quality and fastness.

Chromium Oxide Green may be used for smelting metal chromium and chromium for making stainless steel, auto components , tools, tapes and videos. chromium cross the rust on metal at the same time, strong and stunning. used for enamel, glass industry,developing supplies. particularly for the production of ceramic pigment, vibrant colour products.

At house and abroad, because the global financial recovery, building supplies, coating paint, plastic, ink as well as other industries in the fast development, the demand of inorganic pigment also increase rapidly. with the fast improvement of coating business, as one from the main raw material for inorganic pigment obtained fast improvement. improve the degree of environment safety of inorganic pigment, using has got extensively recognized industry enterprises, environmental protection inorganic pigment development direction from the trend from the times.
